[ARTICLES] The “Witch’s Chin” That Becomes Prominent When Smiling—Restoring Natural Expression Through Mentalis Muscle Repositioning

The so-called “witch’s chin,” a condition in which the chin appears excessively elongated, pointed, or pulled downward when smiling, is not merely a cosmetic concern. In many cases, it originates from abnormal tension and misalignment of the mentalis (chin) muscle. While it may be unnoticeable at rest, facial expressions such as smiling or speaking can cause the chin to sink inward or be drawn downward, a result of overactivity of the mentalis muscle and imbalance with surrounding facial muscles. Recently, mentalis muscle repositioning surgery has gained attention as an effective solution for this condition. Rather than altering bone structure, this procedure repositions and re-fixates the overactive chin muscle to its proper anatomical location, structurally correcting the distortion that appears during facial expressions. Because it can address the witch’s chin deformity without bone resection, patient satisfaction has been notably high. Dr. Jang Yong-jun of ARC Plastic Surgery e...

"Everything about revision facial contouring surgery"


Let's talk more about revision facial contouring.


***


In the first case, the patient visited for a consultation to remove the pin after double jaw surgery.

After CT scans, surgery was planned to improve asymmetry which still remains, and reduce the cheekbone and the length reduction of the chin.


During surgery, all the pins were successfully removed, the cheekbones were reduced to match the proportion, the length of the chin tip was adjusted and the jawline was trimmed as well.



****


The second case is a person who visited for a lifting consultation.
The patient had a previous surgical history of the cheekbone, so we took a CT scan to check the bone condition.

All the pins for fixing the cheekbones were broken or out of place. 
On the right side, the patient still felt uncomfortable in the 45-degree cheekbones when eating.


The current condition of the bone was judged to be one of the causes of facial sagging as well as functional problems, so revision cheekbone surgery was performed.


***


The last case is where the patient decided on revision surgery since didn't feel much improvement in the side cheekbone, especially on the right side
even if she felt a 45-degree change in the cheekbone area.

On the right side, the 45-degree cheekbones were not sufficiently close attached inwards due to the design of the bone fracture line, which was wider than on the left.
The surgical plan was to partially remove a disturbing bone and re-fixate the cheekbones.


During the surgery, the empty space on the upper part of the cheekbone was large, so I compensated the cut-out bone piece changed to a transplant form.
You can see it in the picture the space is sufficiently filled and the CT results are as follows.

As you can see, successful surgery requires a harmonious combination of accurate diagnosis, an optimized surgical plan, safe surgery, and meticulous follow-up.
